How to specify an automatic filling machine before asking for a quotation
A structured brief helps suppliers compare the correct dosing method, automation level, line speed and product-contact design instead of guessing from a product name.
- Product-led selection
- Quote comparison checklist
- FAT and acceptance planning
Eight-step method
Build the automatic filling specification in the right order
Work through each step before comparing machine models or headline speeds.
- 01
Describe the product precisely
Record viscosity at the production temperature, foam, aeration, particles, stringing, abrasiveness, shear sensitivity, chemical compatibility and whether the product settles or separates.
- Current product and safety data
- Representative product sample where practical
- Temperature range and supply method
- 02
Define every fill volume
State the minimum, maximum and common production doses. A machine that reaches the maximum may not be the best choice for repeatability at the minimum.
- Nominal quantities
- Acceptable tolerance or giveaway
- Expected recipe count
- 03
Provide the real containers
Container material, dimensions, opening, stability, shoulder and neck finish affect guide rails, sensors, nozzles and filling speed.
- Drawings, photographs or samples
- Minimum and maximum dimensions
- Any lightweight, unstable or irregular packs
- 04
Set sustained output
Specify containers per minute or per hour at the real dose. Include planned shifts, batch sizes and growth rather than quoting a theoretical peak.
- Current output and labour
- Target output by pack size
- Future capacity requirement
- 05
Agree cleaning and changeover
Define whether the product path will be flushed, stripped, washed, sanitised or cleaned in place, and how quickly the next product must run.
- Cleaning agents and method
- Product recovery expectations
- Allergen or cross-contamination controls
- 06
Map the complete line
List infeed, rinsing, filling, capping, sealing, labelling, coding, inspection, accumulation and end-of-line operations.
- Existing machines to retain
- Required line interfaces
- Available floor space and access
- 07
Define tests and documentation
Decide how fill accuracy, speed, changeover, cleaning and safety will be demonstrated at factory and site acceptance.
- FAT product and container quantities
- Acceptance criteria
- Manual, drawing and certificate requirements
- 08
Compare total project value
Review product suitability, line scope, change parts, training, installation, spares and support—not only machine price.
- Included and excluded scope
- Delivery, installation and commissioning
- Warranty, spares and support response

Quote comparison
Check that proposals are technically equivalent
Use the same data and acceptance conditions for every supplier.
| Topic | What to ask | Why it matters |
|---|---|---|
| Product route | Which dosing principle and why? | Confirms the proposal is product-led rather than catalogue-led. |
| Output | At which product, volume and container? | Prevents comparison of unrelated maximum-speed figures. |
| Accuracy | How is it measured and under what conditions? | Distinguishes repeatability, average fill and legal net-content control. |
| Changeover | Which parts, tools and time are required? | Shows the real production loss between batches. |
| Line scope | What equipment and interfaces are included? | Exposes gaps in conveyors, cap feed, controls and guarding. |
| Acceptance | What will be demonstrated at FAT and SAT? | Creates an objective completion test before delivery. |
Product testing
Use real product and packs when uncertainty is high
Testing helps identify foam, drip, stringing, product starvation, particle damage, container instability and realistic fill speed before the final machine is committed.
- Agree the test product condition and temperature
- Use the intended container and closure
- Test at a representative fill volume and speed
- Record dose results and presentation
- Document any assumptions that remain
Practical answers
Automatic filling machine buying FAQs
Answers are general guidance. Final suitability depends on product trials, containers and the confirmed machine specification.
What should I send when asking for an automatic filling machine quote?
Send product details, safety data where relevant, viscosity and temperature, minimum and maximum dose, container drawings or samples, closure, target output, accuracy, cleaning method, utilities and required line operations.
Should I compare machines by maximum speed?
No. Compare sustained output using your real product, fill volume and container, including indexing, foaming, capping capacity, changeovers and normal line stops.
Is a product trial always required?
Not always, but it is valuable for viscous, foaming, sticky, particulate, abrasive, temperature-sensitive or chemically unusual products.
How many quotations should I compare?
Compare enough credible routes to understand the technical differences. A detailed specification and test criteria are more useful than a long list of prices for non-equivalent machines.

Compare automatic filling proposals on the same technical evidence
A structured worksheet exposes differences in product assumptions, line scope, acceptance testing and lifecycle support before price drives the decision.
Use one evidence schedule for every supplier
A comparison is only meaningful when each proposal answers the same production brief. Record whether an item is included, optional, excluded or dependent on a trial. Where a supplier states a capacity, accuracy or changeover figure, retain the product, dose, pack, test duration and operating assumptions that support it. Unqualified headline figures should not be compared as though they were equivalent.
| Review area | Evidence to request | What a comparable answer should state | Common ambiguity to remove |
|---|---|---|---|
| Product suitability | Trial report, product-path description and material compatibility review | Representative product condition, restrictions, feed method and proposed dosing principle | Suitability based only on product name or a water demonstration |
| Dose and accuracy | Module or range selection, calibration method and test results | Minimum, maximum and common fills; reference method; sample plan; acceptance tolerance | A percentage or accuracy claim without dose and test conditions |
| Output | Cycle breakdown or timed sustained run | Product, fill quantity, containers, head count, accepted packs, rejects, stops and run duration | Nozzle count multiplied by an ideal single cycle |
| Containers and closures | Approved samples, change-parts list and handling concept | Dimensions, variation, guides, sensors, closure placement/capping method and rejected-pack route | Quote based on a photograph without production samples |
| Cleaning and recovery | Product-contact diagram, cleaning method and observed demonstration | Strip-down, flush or CIP boundary; cleaning agents; recovery; verification and parts handling | “Easy clean” without a task, access route or acceptance check |
| Line integration | Layout, interface schedule and control narrative | Infeed, filler, capping, labelling, coding, inspection, accumulation, utilities and line states | Filler-only speed quoted for a complete line |
| FAT/SAT and documents | Test protocol, supplied document index and open-item process | Product/pack matrix, acceptance criteria, site-dependent tests, manuals, drawings and handover records | A generic FAT that does not test the quoted performance |
| Lifecycle support | Spares list, training scope, warranty boundary and service route | Included parts, consumables, operator/maintenance training, response route and exclusions | Machine price compared without change parts, installation or support scope |
Plan a representative sample trial
The sample plan should include the conditions most likely to expose a poor match: the smallest and largest dose, least stable container, narrowest opening, product at the edge of its normal temperature range and any particles, foam, dust or stringing that affect the fill. Trials should also check start-up, a planned pause, product refill and the end of a batch where those states change feed stability.
Record more than the final quantity. Inspect container presentation, nozzle clearance, splash, foam, drips, rim cleanliness, product damage, dust, reject handling and the effort needed to recover and clean the product path. An agreed photo, video or signed data record makes later quotation comparisons more reliable.
Write measurable acceptance criteria
Criteria should identify the product and pack, reference instrument, sample frequency, sustained run, accepted and rejected pack rules, changeover task, cleaning demonstration and allowable open items. FAT should prove what can be represented before delivery; SAT should close site-dependent utilities, retained-equipment interfaces and production conditions.

Further buyer questions
More automatic filling machine buying questions
Use the same assumptions and evidence schedule when comparing suppliers.
What should be treated as a quotation assumption rather than a confirmed specification?
Anything not supported by representative samples, drawings, agreed product data or a defined test should remain an assumption. Mark it clearly, assign who must verify it and avoid treating it as accepted performance.
How can buyers compare quoted accuracy fairly?
Use the same product, dose, container, reference instrument, sampling method, operating temperature, run condition and acceptance rule. A percentage without those conditions is not a comparable result.
Complete the evidence pack
Add commercial scope, site readiness and ownership to the machine specification
A technically detailed filling brief still needs a clear project boundary. Record what the supplier is expected to provide, what the site provides and which facts remain conditional on trial or design review.
| Evidence pack section | Include | Use it to control |
|---|---|---|
| Automation business case | Current method, staffing, batch pattern, available production time and reason for change. | Whether semi-automatic, compact automatic or integrated operation is justified. |
| Commercial comparison | Base duty, options, exclusions, assumptions, trials, documentation, installation and acceptance. | Like-for-like quotation review and controlled value engineering. |
| Application evidence | Product data, samples, packs, closures, dose method, difficult conditions and trial record. | Technology, nozzle, product path and format selection. |
| Layout and site | Dimensioned area, delivery route, utilities, product feed, drainage, extraction and connected equipment. | Installability and responsibility at physical boundaries. |
| Acceptance and handover | FAT/SAT methods, samples, reference instruments, training, documents, backups and open-action control. | Objective release rather than subjective demonstration. |
| Lifecycle support | Cleaning, maintenance, critical spares, part identification and escalation route. | Reliable operation after commissioning. |
Compare automation levels
Use labour, run length, pack handling and changeover to choose the operating model.
Compare quotation scope
Identify the product, pack, control, integration and evidence factors that change project cost.
Prepare the site
Check access, operating envelope, utilities, product supply and SAT readiness before delivery.
Send one controlled brief to every supplier
Use the same product, pack, output, cleaning, interface and acceptance assumptions so quotations can be compared technically rather than by headline description.
